This study begins with emphasis on the approach to public policy development and the extent to which a GIS framework can be used to evaluate projects objectively. This paper relates to public policy making and the use of GIS as a strategic management tool rather than the development of GIS technologies which has been the focus of attention since the advent of the first generation GIS systems in the 1960s. In order to consolidate a view towards public policy, the aim of this study is to show the advantages of using GIS to generate results which could be evaluated by cost and benefit analysis giving options of the alternative methods to estimate the feasibility of projects (both tangible and intangible) in a real public policy scenario. This study also reports that the tangible benefits associated with the GIS projects are better information processing, the easy analysis of data and the cost savings of map updates and printing, whilst the intangible benefits include quality decision making, and precise management of data through computing networks. In GIS context, the task of analysing and evaluating GIS projects is assumed in order to facilitate scientific and quantitative cost-benefit analysis. Previous methods of the cost-benefit analysis has not fully supported the evaluation of the intangible benefits and it has not been possible to make public policy realistic or scientifically understandable limiting decision makers in public domain. With the GIS decision makers are able to explore the potential of projects with this powerful decision supporting tool in practical application. On the basis of its potentials and limitations to cost-benefit analysis, therefore, it can be concluded that more flexible analysis and evaluation methodologies are needed to extend into the intangible benefits. In order to balance the evaluation of both quantitative and qualitative approaches on the cost-benefit analysis new or additional utilities will be required for the next GIS generation appraisal tool.
This paper focuses on the process of national family politics through the project of family planning which became one of the main factors that brought the structural change in Korean families after 1960's. The family planning was established under the national project which was tightly driven by the government, and the new families were built artificially and coercibly by the plan rationality. The various and diverse forms of the national family politics were revealed in the process of the project. For example, the image of the modern families was forcedly adopted in order to justify the project, the families in this period were under microscopic surveillance in order to accomplish th e project effectively , etc. Modern nuclear families were derived through the economical and social support on the families only with a few number of children, and the structural change was made through the medical technique and support. Consequently, during the forty years after the project, the size of the families were reduced drastically, various and diverse forms of families were generated, and the modern family action and value were wide spread and generalized. Through the project, the government has been establishing th family patterns and norms which were so suitable to the modernization project that the families were able to be pulled into public sphere. The family problems in this process became very serious. However the government repeatedly forced the families to be the reoresentative of welfare state through new-modern political discourses. The welfare through the family is coerced to replace the weakness of welfare state. However the family is not the subject of the welfare, but the object of the welfare. The governmental family politics must make more efforts to gave the families to be the object to the welfare.
Miscanthus are perennial rhizomatous grasses and considered as an ideal cellulosic bioenergy crop. Recently, it was reported that Miscanthus was damaged by the larvae of rice stem borer, Chilo suppressalis Walker, one of the most destructive pests of rice in Korea since the 1960s. This study was thus conducted to evaluate the insecticidal effects against rice stem borer in the Miscanthus cultivation fields for two years. The experiment consisted of four chemical agent plots, one environment-friendly agent plot, and untreated plot. Untreated plot showed significantly high damage of 50%, while Buprofezin Tebufenozide and Carbosulfan Methoxyfenozide treatment plots showed low damage rate of 2% with low larvae density of 1 and $2.3larvae\;m^{-2}$, respectively. Damage rates of Tebufenozide, ChlorantraniliproleIndoxacarb, and environment-friendly agent(MatrineWood vinegar solution) were 15, 26, and 18%, respectively, which were lower than that of untreated plot but higher than those of Buprofezin Tebufenozide and Carbosulfan Methoxyfenozide. In conclusion, rice insecticides were effective against rice stem borer in Miscanthus field. In particular, the treatments with Buprofezin Tebufenozide and Carbosulfan Methoxyfenozide showed excellent control effects with control value of 93.3 and 95.2. However, further studies with different types of insecticides should be carried out for the selection of insecticides with more effective control of rice stem borer.

Since the 1960s, Korea has achieved rapid economic growth, longer life expectancy, accelerated urbanization and a westenization of diet. Cardiovascular disease has become the leading cause of death; however the prevalence of ischemic heart disease(IHD) remains low. A cross-sectional multiphasic screening service for 18,426 persons aged $30\sim64$ years in a Medical Aid Program in Kyonggi-do Province was conducted from 1991 to 1993. Total cholesterol(TC), fasting blood glucose(FBG), blood pressure(BP), and electrocardiographic(EKG) data were collected. The result as follows ; 1. On the EKG findings, the age-adjusted prevalence of myocardial ischemia and myocardial infarction was 1.45% in men and 2.06% in women. 2. The mean blood pressure was 122.9/78.8mmHg. The age-adjusted prevalence of hypertension was 11.05% in men and 9.02% in women. The prevalence of hypertension showed increasing tendency according to age increase. In all age group, the prevalence of hypertension was higher in men than women. 3. The mean total cholesterol level was 184.4mg/dl in men and 189.2mg/dl in women. The age-adjusted prevalence of hypercholesterolemia was 4.88% in men and 5.67% in women. The total cholesterol level showed increasing tendency according to age increase, except $55\sim64$ age group in men. 4. The prevalence of hyperglycemia is 5.8%. The age-adjusted prevalence of hyperglycemia is 6.72% in men and 4.50% in women. The prevalence of hyperglycemia showed increasing tendency according to age increase. 5. On the EKG findings, the prevalence of myocardial ischemia and myocardial infarction was higher in hypertension than normal, in all age group of men and women less than 40 years-old. Only in women more t]fan 40 years-old, the prevalence of myocardial ischemia and myocardial infarction was higher in hypercholesterolemia and hyperglycemia. Nevertheless there is not statistical association between ischemia heart disease and previous risk factors in other age group, the prevalence of myocardial ischemia and myocardial infarction was higher in hypertension, hypercholesterolemia and hyperglycemia than normal. The result of this study suggest that relationships between major risk factor of ischemic heart disease and ischemic heart disease is similar to existing theory.
Apple Marssonina blotch, caused by Diplocarpon mali, which has been increasing on apple trees and become one of the most serious diseases on apple trees in Korea since the begining of 1990's. In this study, ecology of Marssonina blotch including disease incidence and spore dispersals was surveyed from 1992 to 1995 in Kyungpook, and factors influencing the incidence of the disease were analyzed. Marssonina blotch began to occur on apple leaves in June and was observed commonly in most of apple orchards after August, and increased rapidly in September. The incidence of this disease was high at the year of low temperature and a lot of precipitation. The conidia discharge began to occur in May and continued to October, and the peak period of spore release was in August and usually more than 70% of total spore release of the year released from August to September. The incidence of the disease was high in the northern and mountain are as such as Yeongjoo, Chungsong, Andong, and relatively low in the southern areas such as Kunwi, Yongchon. Jonathan cultivar was the most susceptible to Marssonina blotch, and Jonagold, Sekaiichi was secondly susceptible and the next Fuji was more susceptible than Tsugaru. The incidence of the disease was relatively high in orchards which cultivation management of irrigation, drainage, air circulation, fertilization, and fungicide spraying were poor.

The land use in suburban area has been changed rapidly due to the urban expansion in Korea during the last few decades. And such land use changes result in various environmental problems such as biodiversity decrease, habitat fragmentation, air pollution and urban heat island. Remote Sensing (RS) and Geographical Information Systems (GIS) can be used for land cover change detection to understand the impact and trend of the land use change. Change detection is the process of identifying differences in the state of an object or phenomenon by observing it at different times and it can provide quantitative and comparative information for the land use/cover change. RS is less expansive than field survey for producing land use maps, and can be accessed quickly and repetitively for large area. Also it can be used for change detection using multi-temporal land use/cover by accumulated data. Therefore, the purpose of this study is to detect and quantitatively evaluate urban land cover change in urban stream watershed area for the last few decades and ultimately to provide the basic data for urban land use planning and management.
Prediction of a stock price has been a subject of interest for a long time in financial markets, and thus, many studies have been conducted in various directions. As the efficient market hypothesis introduced in the 1970s acquired supports, it came to be the majority opinion that it was impossible to predict stock prices. However, recent advances in predictive models have led to new attempts to predict the future prices. Here, we summarize past studies on the price prediction by evaluation measures, and predict the direction of stock prices of Samsung Electronics, LG Chem, and NAVER by applying various machine learning models. In addition to widely used technical indicator variables, accounting indicators such as Price Earning Ratio and Price Book-value Ratio and outputs of the hidden Markov Model are used as predictors. From the results of our analysis, we conclude that no models show significantly better accuracy and it is not possible to predict the direction of stock prices with models used. Considering that the models with extra predictors show relatively high test accuracy, we may expect the possibility of a meaningful improvement in prediction accuracy if proper variables that reflect the opinions and sentiments of investors would be utilized.

To research the changes of Ramyun in Korea, this paper was went over an historical study through the content analysis of ads. from 1963 to 2012. The study period was divided into 6 stages based on GNI(Gross National Income). The advertisements were classified into new advertisements and all ones, and the advertisements of new Ramyun were categorized with 4 ways. And the most emphasized messages of advertisements and advertising models of each periods were also examined. The total number of new advertisements was 185(3.7/y) and 650 total advertisements(13.7/year). The most emphasized messages were changed from 'taste' and 'high calorie' to 'noodles', 'function(specific nutrition)'. The advertising models were actors, comedians, popular singers, in turn. The 1960's was the period when the fewest new products were advertised to consumers most often. 1980-1996 was the period when the most new products were advertised the most. During the depresseions, all ads were more frequently and new ads were lower advertised. Above results, each period was named as follow, respectively ; the Expansion period(1963~1969), the Set-up period(1970~1979), the Competition period (1980~1987), the Bipolarization period(1988~1997), the Transition period(1998~2003), the Stabilization period(2004~2012).
It is generally acknowledged that Philippines politics has achieved a basic soil for democracy at the macro-level by the two incidents of 'People Power' (1986 & 2001). However, in spite of such an achievement, Philippine politics at the micro-level, does not enjoy the same reputation. Institutionalized 'Bossism' or 'patron/clientelism' political culture has been attributed to make such a gap. This paper aims to bridge the gap by a longitudinal observation on local politics of a particular province in the Philippines. Surigao del Norte is the province picked up for the study. The reason why this particular province attracts special concerns is that there appears to come a very dynamic local politics, led by an indigenous Christian organization, the PBMA (Philippines Benevolent Missionary Association), which was founded in the mid 1960s. With the coming of the organization in the province, the political power of the traditional families has been narrowed. On the other hand, new families, not only the leader family of the PBMA but also the family allied with the PBMA, has expanded political influence. Following steps are adopted to understand the meaning of such a change. First, institutional frame of Philippine politics and elections will be reviewed. Second, demographic changes will be investigated on Surigao del Norte province to find out how popular the PBMA organization is among the people. Third, local election outcomes will be examined to describe the changing nature of political landscape of the province. This will reveal how the relationship between the old and new families has been developed in the province. Lastly, based on the facts discovered by a longitudinal observation, an attempt to evaluate theories on Philippines politics will be made Conclusions are as follows. To understand the dynamics of Philippine politics, 'expectations from the below,' or, 'passions of the people,' suggested by Ileto, needs more attention. Furthermore, 'mutual accommodation' between domination and resistance, coined by Abinales, also demands more appreciation. The case of local politics in the Surigao del Norte, with the coming of the PBMA, is sure to show a concrete example of changing politics in the 'changeless land.'
